Unraveling Countenance

Enchant Permanent
At the beginning of each end step, put a
Machination counter on Unraveling
Countenance.
Enchanted creature gets -X/-X where X is the
number of Machination counters on Unraveling
Countenance.
Whenever you put a Machination counter on
Unraveling Countenance, chose an ability on
enchanted permanent. It loses that ability until
Unraveling Countenance leaves the battlefield.
